Definitions
- the present invention relates to an apparatus and method for diluting concentrated detergent and performing rinse operation with the same.
- a reaction cuvette is rinsed by using detergent with certain concentration.
- detergent is generally kept in a concentrated state when it is being transported and stored. Therefore, in order to obtain the detergent with appropriate concentration, the full-automatic biochemical analyzer also provides a function to automatically dilute the concentrated detergent before it is used to rinse the reaction cuvette. In this way, biohazards caused by manual operations may be avoided.
- the dilution of detergent refers to uniformly mix the concentrated detergent with deionized water in a certain volume ratio.
- Conventional diluting methods include on-site dilution and liquid-storage dilution.
- on-site dilution the detergent is not diluted until the reaction cuvette is going to be rinsed. In this case, all the diluted detergent produced in a dilution process would be used up one time during the subsequent rinsing process of the reaction cuvette.
- a certain amount of detergent is diluted and stored in advance, and then the diluted detergent would be used at any time thereafter for rinsing the reaction cuvettes.
- the drawbacks of the on-site dilution lie in that the biochemical analyzer operates too frequently, and in that the dilution ratio is difficult to be guaranteed since the amount of diluted liquid for each dilution process is very small and thereby the flow rate is difficult to control.
- the liquid-storage dilution can accurately control the flow-rate and decrease the frequency of biochemical analyzer's operation. Therefore, the liquid-storage dilution is widely applied.
- liquid-storage dilution In conventional liquid-storage dilution, it is typically by means of dosing pumps, injectors, high-pressure gas or gravities of their own, to drive the deionized water and the concentrated detergent into a liquid-storage container. But, the dosing pumps and injectors are costly, while driving with gravities of their own is not reliable and difficult to quantify. For this reason, the liquid-storage dilution driven by high-pressure gas is becoming popular.
- the liquid-storage container is required to be kept in a low pressure (e.g., environmental pressure) during a dilution process, so that deionized water and concentrated detergent can be driven into a liquid-storage container by high-pressure gas. Then, during a rinsing process, the liquid-storage container is required to be kept in a high pressure, since the diluted detergent within the liquid-storage container should be driven into a reaction cuvette, which is kept in a low pressure. In order to avoid interference between the diluting and rinsing processes, the two processes are carried out separately, i.e., within two separate containers and having two separate sets of apparatus for control. This results in high cost and high complexity of a system for both diluting and rinsing.
- a low pressure e.g., environmental pressure
- the diluting process is not triggered until diluted detergent within the liquid-storage container is used up. Only when it is used up, a predetermined amount of deionized water and concentrated detergent are driven into the liquid-storage container. As a result, the diluting process would not be triggered if the diluted detergent within the liquid-storage container is consumed partly. Further, even if a diluting process is triggered, the dilution ratio cannot be guaranteed due to inability to determine the amount of deionized water and concentrated detergent that need to be driven into.
- An object of the present invention is to provide an apparatus for auto-diluting and rinsing, which is capable of carrying out a dilution process and a rinsing process within the same liquid-storage container.
- Another object of the present invention is to provide an apparatus for auto-diluting and rinsing, which enables the diluting process to be triggered at any moment while keeping the dilution ratio.
- an auto-diluting and rinsing apparatus comprises: a concentrated detergent container for holding concentrated detergent to be diluted; a diluter container for holding diluter, which is used to dilute the concentrated detergent; and a diluted detergent container for holding diluted detergent for rinsing, which are formed by mixing the concentrated detergent and the diluter; wherein the concentrated detergent container and the diluter container are communicated with a high pressure gas source, respectively, and the apparatus further comprising: a gas path controller, configured to control the diluted detergent container to be communicated with a low pressure gas source via a first gas path during a dilution process; and to be communicated with a high pressure gas source during a rinsing process.
- a method for auto-diluting and rinsing is also provided, which is carried out by an auto-diluting and rinsing apparatus, the apparatus including a concentrated detergent container for holding concentrated detergent to be diluted; a diluter container for holding diluter; and a diluted detergent container for holding diluted detergent; and the method comprising the following steps: causing the concentrated detergent container and the diluter container to be communicated with a high pressure gas source, respectively; causing the diluted detergent container to be communicated with a low pressure gas source; causing the concentrated detergent and the diluter, for a dilution process, to be alternately driven into the diluted detergent container via a first and second liquid path, respectively, by alternately opening the first and second liquid path, so as to obtain the diluted detergent; blocking the first and second liquid path after the dilution process; and causing the diluted detergent container, for a rinsing process, to be communicated with a high pressure gas source, so

- FIG. 1 is a schematic diagram showing the configuration of an auto-diluting and rinsing apparatus 10 according to an embodiment of the present invention.
- the auto-diluting and rinsing apparatus 10 comprises: a concentrated detergent container 1 for holding concentrated detergent; a deionized water container 2 for holding deionized water; and a diluted detergent container 3 for holding diluted detergent.
- the concentrated detergent container 1 and the deionized water container 2 are communicated with the diluted detergent container 3 via a first and second liquid path, respectively, so that the concentrated detergents and the deionized water can be driven into the diluted detergent container 3 , respectively.
- the concentrated detergent container 1 is communicated with a high-pressure gas source 7 via a pressure-regulating valve 4
- the deionized water container 2 is also communicated with the high-pressure gas source 7 via a pressure-regulating valve 5 .
- the pressures of the two containers 1 and 2 are kept in a high pressure.
- the containers 1 and 2 can also be communicated with two separate high-pressure gas sources, respectively, as desired.
- the diluted detergent container 3 is connected to a common (COM) terminal of a three-way solenoid valve SV 03 .
- the normally open (NO) terminal of the valve SV 03 is communicated with the high-pressure gas source 7 via a pressure regulating valve 5
- the normally closed (NC) terminal of the valve SV 03 is communicated with a low-pressure gas source 8 (e.g., atmospheric environment).
- the diluted detergent container 3 is communicated with the low-pressure gas source 8 for dilution.
- the valve SV 03 is turned off, that is, the COM terminal of the valve SV 03 is communicated with the NO terminal thereof (i.e., the second gas path is open)
- the diluted detergent container 3 is communicated with the high-pressure gas source 7 for rinsing.
- the three-way solenoid valve SV 03 in the embodiment depicted in FIG. 1 can be replaced with at least two two-way solenoid valves, where one is a normally open type of valve NO, and the other is a normally closed type of valve NC, with the normally open type valve NO provided on the first gas path and the normally closed type valve NC provided on the second gas path.
- the concentrated detergent container 1 is communicated with the diluted detergent container 3 via a two-way solenoid valve SV 01 , which is a normally close type of valve; and the deionized water container 2 is communicated with the diluted detergent container 3 via a solenoid valve SV 02 , which is a normally close type of valve.
- the valve SV 01 and SV 02 may be turned on or off in sequence, so that the concentrated detergent and the deionized water can be alternately driven into the diluted detergent container 3 under a high-pressure gas.
- the duration in which the valve SV 01 /SV 02 is turned on corresponds to the amount of the concentrated detergent/the deionized water that has been driven into the container 3 .
- the volume ratio between the concentrated detergent and the deionized water i.e., dilution ratio
- the apparatus 10 may further include an upper-liquid-level sensor (not shown), which is provided within the diluted detergent container 3 .
- the upper-liquid-level sensor is used to detect whether the liquid level of the diluted detergent within the container 3 reaches a predetermined position, for preventing the overflow of the detergent.
- the valve SV 01 and SV 02 can be turned on alternately until the upper-level sensor detects that the predetermined position is reached. That is, the diluting process will keep on until desired amount of diluted detergent is obtained in container 3 , without judging the amount of the concentrated detergent and the deionized water driven into the container 3 .
- a filter 6 is further provided on the first liquid path between the concentrated detergent container 1 and the diluted detergent container 3 , for filtering any crystal that may be contained in the concentrated detergent.
- the diluted detergent container 3 is further communicated with a reaction cuvette 9 via a solenoid valve SV 04 .
- the reaction cuvette 9 is kept in a low pressure, such as atmospheric pressure.
- the valve SV 04 is turned on, and thus the reaction cuvette can be rinsed.
- the apparatus 10 may further include check valves CV 01 and CV 02 .
- the check valve CV 01 is arranged between the diluted detergent container 3 and the concentrated detergent container 1 ; and the check valve CV 02 is arranged between the diluted detergent container 3 and the deionized water container 2 .
- these check valves are used to prevent the diluted detergent from backflow, i.e., from being driven back to the deionized water container 2 and the concentrated detergent container 1 .
- a check valve CV 03 may also be arranged between the diluted detergent container 3 and the reaction cuvette 9 , so as to prevent the liquid in reaction cuvette 9 from backflow to the diluted detergent container 3 .
- the pressure of the high-pressure gas source is relatively high with respect to that of the low pressure gas source.
- the pressure values for each of the gas sources may be determined based on practical requirements. But it is required to have a pressure difference between the two gas sources, so that the liquid in the concentrated detergent container 1 and the deionized water container 2 can be driven into the diluted detergent container 3 under the high pressure gas.
- the low-pressure gas source may be the atmospheric environment.
- FIG. 2 shows an example of diluting and rinsing processes performed by the auto-diluting and rinsing apparatus according to the present invention.
- the solenoid valve SV 03 is normally closed, i.e., its COM terminal is communicated with its NO terminal.
- the diluted detergent container 3 communicates with the high-pressure gas source 7 and thus it is kept in a high pressure.
- step S 21 the solenoid valve SV 03 is turned on, that is, communicating the COM terminal with the NC terminal thereof, and thus the diluted detergent container 3 is communicated with the low pressure source 8 (atmosphere). As a result, the pressure in the diluted detergent container 3 is released gradually (step S 21 ).
- the solenoid valve SV 02 When the pressure in the diluted detergent container 3 is released to the environmental pressure, the solenoid valve SV 02 is turned on and thus the second liquid path between the deionized water container 2 and the diluted detergent container 3 is open. At this time, since the pressure in the deionized water container 2 is higher than that in the diluted detergent container 3 , a certain amount of deionized water can be driven into the diluted detergent container 3 under the pressure difference between the containers 2 and 3 (step S 23 ).
- the solenoid valve SV 02 Upon the certain amount of deionized water is completely driven into container 3 , the solenoid valve SV 02 is turned off to block the second liquid path, and then the solenoid valve SV 01 is turned on to open the first liquid path between the concentrated detergent container 1 and the diluted detergent container 3 .
- a certain amount of concentrated detergent can be driven into the diluted detergent container 3 under the pressure difference between containers 1 and 3 (step S 25 ).
- the driven concentrated detergent is mixed with deionized water driven previously to dilute the concentrated detergent.
- the solenoid valve SV 01 is turned off to block the first liquid path.
- the pressure in the diluted detergent container 3 keeps at an atmospheric pressure.
- the valve SV 03 is turned off, that is, the COM terminal is communicated with its NO terminal, and thereby the diluted detergent container 3 is communicated with the high pressure gas source 7 , so that the pressure in the diluted detergent container 3 increases (step S 27 ).
- valve SV 04 Upon the pressure in the diluted detergent container 3 reaches a certain high value, the valve SV 04 is turned on. Thus, a certain amount of diluted detergent is driven under a high-pressure gas into the reaction cuvette 9 for rinsing (step S 29 ). After the desired amount of the diluted detergent is completely driven into the reaction cuvette 9 , the valve SV 04 is turned off.
- the auto-diluting and rinsing apparatus may be configured to operate in such a way that the rinsing process is carried out immediately after the dilution process.
- the diluted detergent, obtained in the dilution process may be hold in the container 3 for future usage of rinsing.
- valves SV 01 , SV 02 , SV 03 and SV 04 on respective liquid paths and gas paths are turned on or off, under the control of a predetermined control timing.
- the ratio between the turn on duration of the valve SV 01 and that of SV 02 i.e., opening duration of the respective liquid path
- the dilution ratio is 1:2, i.e., the volume ratio of the concentrated detergent and deionized water is 1:2.
- the concentrated detergent of 1 ml and the deionized water of 2 ml into the container 3 .
- the solenoid valve SV 02 is first turned on for 0.2 s and then turned off, and subsequently the solenoid valve SV 01 is turned on for 0.1 s and then turned off.
- the cross-sections of the valves SV 01 and SV 02 have the same area and the flow rates of the liquid thereof are same too.
- valves SV 01 and SV 02 may be turned on and off periodically, and thereby alternately driving the concentrated detergent and deionized water into container 3 for many times. Such a multiple alternate driving method may continue until the upper-liquid-level sensor provided within the container 3 detects that the liquid level of the diluted detergent has reached the predetermined position.
- valves SV 01 and SV 02 are turned on and off under control signals having two different control timings, which are cooperated with each other, as shown in FIG. 3A .
- both of valves SV 01 and SV 02 are turned on when the control signal is set to a high level, and only one of the two valves is turned on at the same time.
- the turn on duration (opening duration of the liquid path) for the valve SV 02 is two times of that for the valve SV 01 during each cycle.
- the valves SV 01 and SV 02 can be controlled only by a single timing, as shown in FIG. 3B . In FIG.
- valve SV 01 is turned on when the control signal is set to a high level; and the valve SV 02 is turned on when the control signal is set to a low level.
- the valve SV 01 is turned on while the valve SV 02 is turned off, and vice versa.
- the turn on duration for valves SV 01 and SV 02 is set based on the dilution ratio, that is, the turn on duration for valves SV 02 is two times of that for valve SV 01 during each cycle.
- the concentrated detergent and deionized water may be driven into container 3 in very small amount for each time, while the dilution ratio can be guaranteed.
- a small amount of diluted detergent can be acquired repeatedly, and such a dilution process may continue until the liquid level in the diluted detergent container 3 reaches an upper-liquid-level float (i.e. an upper-liquid-level sensor). In this way, the dilution process can be triggered at any moment while keeping the dilution ratio.
- the multiple alternate driving method as described above may also be applied to the conventional diluting apparatus to trigger the dilution process at any moment.
- diluting and rinsing processes can be carried out within the same diluted detergent container, which reduces the costs and complexity of the system, and ensures that the diluting process and the rinsing process do not interfere with each other.
- the controllers (such as SV 01 ⁇ 04 ) arranged in respective liquid paths and gas paths may be controlled and adjusted based on a preset control timing, which controls the turned on duration for each of the first and second liquid paths according to the desired dilution ratio, so that the amount of concentrated detergent and deionized water that have been driven into the container 3 can be well controlled, and thus the desired dilution ratio can be achieved easily. Therefore, diluting process may be triggered at any moment while keeping a constant dilution ratio.
